DEMOUNTABLE BIM FOR VEHICLE WHEELS.

Application 'tiled Hay 27, 1925. i Serial No. 33,131.

To all whom, it muy concern:

Be it known that I, GEORGE Houma, a citizen ot' the United States, residing at Newmarket, in the county of Rockingham and State of New Hampshire, have invented new Yand useful Improvements in Demountable Rims for Vehicle lVheels, of which the followingis a specification. V

This invention relates t0 a vehicle wheel including a demountable rini separably engagged with a pneumatic or other resilient tire. The invention is embodied in certaln improvements in the construction of the rim, whereby the rim is conveniently and y securely engaged with the tire and with the Wheel, and simplicity ot' construction is obtained.

the accompanyingf drawings foi-miner a part of this speciticationf eigure 1 is e sectional view ol a wheel including a demountable rim embodying the invention. e

.Figure 1 is a fragmentary view, similar i to a portion of Figure 1.

Figures 2 and 3 are side views of the inner and outer rings shown in section bylFigure 1.

Figure Il is a section on ure 2.

`lfiggjure 5 is a Sectiony on line .5f-5 of Figure 2.

Figure 6 is ure 3,

Figure 7 is a section on line 7--7 of Figure 3.

The same reference characters indicate the saine parts in all of the figures.

The :telly 12 of a wheel with which my im roi/ed rim cooperates is provided With evelierl peripheral face 13, extending from the outer side to an external stop bead 13t at the inner side ot' the felly. The rim line 4 4 of Figa section on line 6 6 of Fign is composed of an inner ring' l5. and an out-er ring-16, each provided at its outerf' edge With a flange 17, formed to confine a tire shoe. The inner ring 15 has an internal stop bead 15a, abutting the bead 13* and its inner surface overhangs the face 13 of 'the folly, end is seV a-rated therefrom by an ennular recess igure la). The ring 15 is provided at its outer edge with an inwardly projecting locking bead 18, on which is formed tongue 19.'

The outer ring 16 is rovided with an inner side fece 20, forme to bear onthe outer an inwardly projecting looking .provided Nwith clamps 30,

edge ot' the 'telly face 13, and enter the recess- 25. and with a, peripheral locln groove 21, formed to receive t e locking bea 18. Thejring 16 is also provided with e locking slot 22, adapted to receive. the lockingr tongue 19. The outer ring 16 is resilient and noneontinuous. so that it is adapted to be flexed or distorted, and to normally assume a cirl cular torni, the ring,r being' interru ted at so that it has free ends EB, which are movable relative to each other, distortion ot' the ring.

The tire shoe 26 may be placed on the inneiiringr 15, either before or after the ring is placed on the folly. When the ring 15 is in its predetermined and the recess 25 is formed, the outer ring 16 is suitably manipulated to lock it to the inner ring; and seat its side face 20cm the outer edge ot' the face 13 of the felly. This manipulation involves asuitable distortion ot' the ring 16, to cause its slot 22 to slip on to the lockingy ear 19. After this, the ring 16, in assuming its normally circular form, enters the recess 25, so that the groove 21 receives the locking bead 18, and the side faceQO is eltedonthe fell The follyv is hearing on outer ring; 16, as shown by Figure 1. I The rings are now securely engaged Wit each other and with the telly. The rings may be separated from eachother hy removing the clamps 30, distorting the ring 16 to remove its slot from the tongue 19, and

to permit a then withdrawing the ring from`the recess `the free ends of thc"ring adapted to receive a prying tool, iwhereliy relative dicplecement et' said ends may he effected.

For use with a vehicle wheel Whose folly has` a hevelleol peripheral face and au extermal stop bead at the inner edge thereof; a. two-part demonntable rim comprisin yan inner ring embracing the periphery olfl ',fih'e folly and rovidedA with an externall tire confinine range, said ring having at its inner edge an internal stop bead adapted to bear on the stop bead ofthe telly, and at its outer edge en inwardly projecting looking head and a locking tongue projecting inward from the head, the inner rinfr being spaced from the peripheral linee of tlic telly position on the telly,
